Last NHL game I attended, it was similar...lift up my sweater so they could see my waistline. Period. Last college football game I attended, they were more concerned about finding alcohol being smuggled in than anything else. Looked through my binoculars to make sure they weren't one of the flasks.
But, if there are a couple of judgments against these places, that would all change. Either out of business as cordex suggested, or the whole nine yards. May be a good time to invest in companies that sell metal detectors...
